The Asunder Project - an extensible DHT framework
2005-04-05 - After much delay, development has picked up again. The project is being refactored in order to be tested thoroughly with JUnit, and to permit more efficient simulations.
2005-12-31 - There have been significant improvements in the routing algorithm, although no test application is yet available. Javadocs can now be viewed for Asunder here.
2005-12-11 - Latest simulation runs a DHT network of 6 nodes. Content is published and retrieved successfully, although the caching algorithm used by the nodes need to be improved significantly.
Currently in CVS. Check back periodically for an alpha release.

Plans are underway to publish an actual tutorial
